How do you set the name of a blob file in JavaScript when force downloading it through window.location?

function newFile(data) {
    var json = J

This is my solution. From my point of view, you can not bypass the .

function export2json() {
  const data = {
    a: '111',
    b: '222',
    c: '333'
  };
  const a = document.createElement("a");
  a.href = URL.createObjectURL(
    new Blob([JSON.stringify(data, null, 2)], {
      type: "application/json"
    })
  );
  a.setAttribute("download", "data.json");
  document.body.appendChild(a);
  a.click();
  document.body.removeChild(a);
}
